Video Input

PyTouch provides a video handler class which loads videos obtained from sensors.

It allows for some basic functionality such as:

• Resizing video
• Video information (frame position, and total frame count)
• Stepping through the video by consecutive frames
• Skipping frames or extract specific frames

Usage

An example is shown below on the usage of VideoHandler

from pytouch.handlers import VideoHandler

my_video = VideoHandler("/path/to/video.mp4")

Consecutive frames from the video can be obtained by,

# Both frame and curent frame position are returned

frame, pos = my_video.get_frame()

The frame information can be queried and frame position set,

current_frame, total_frames = my_video.frame

skip_frames = 10

next_frame = current_frame + skip_frames

if next_frame <= total_frames:

my_video.set_frame_pos(next_frame)

my_video.get_frame()

The video can be resized to return frames with a custom (Width, Height),

new_width = 64

new_height = 64

my_video = VideoHandler("/path/to/video.mp4", resize=(new_width, new_height))
